To all whom it concern:

Be it known that we, CHARLES H. HAcxnrr and THOMAS W. MORGAN, citizens of the United States of America, and residents of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Adjustable Cream-Exits for Centrifugal Cream-Separators, of which the following is a specificaticn.

Our invention relates to improvements in adjustable cream-exits for centrifugal cream separator bowls, and the object ofour improvement is to provide means whereby the receiving end of the cream-exittube may be adjusted radially toward or from the axis of the bowl. This object we have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Figure l is a central vertical axial section of the cover of a centrifrifugal cream separator bowl, taken through the center of the adjustable creamexit-tube therein. Flg. 2

is an upper plan view of the same.

Similar reference characters refer to similar parts throughout the several views.

We have shown at d the cover of a centrifugal. cream separator bowl, of an ordinary type, said cover being convex with a cylindrical upwardly directed extension h with a central axial opening f to be used as a milkinlet.

A cream-exit tube or orifice c is located in said cylindrical extension, parallel with the axis of the cover, and its upper portion is interiorly threaded to receive the exteriorly threaded plug a. The plug may be turned to move it longitudinally within the orifice 0, by means of a screw-driver inserted in the slot g.

An outwardly opening hollow or well 6 is drilled in the center of the top of said plug and extends but a short distance therein. This well being located axially, an orifice I) is drilled obliquely from the center of the bottom of said well downward so that its lower end comes to the lower edge of the plug. When the plug is given a quarter turn from the position shown in Fig 1 in either direction the location of the lower end of the orifice Z) is adjusted in a direction farther away from the axis of the bowl, and is moved towards such axis when the plug is turned back, the limit of adjustment being the distance equal to a semi-diameter of said plug.

. The object of this radial adjustment in distance toward or away from the axis of the bowl, is to permit the receiving-end of the orifice b to draw from the inner richer zone of cream or from some other portion of the cream zone where the cream has more or less of an admixture of milk, so that the skimmed cream may be of a desired. degree of dilution.

Having described our invention, what we claim as new, and desire to secure by Letters Patent is;

In a device of the character described, the combination with a cream separator cover having a milk inlet andan outlet channel formed therein, of a vertically movable plug threaded into the outer end of said channel, there being a centrally disposed well formed in the upper face of said plug, and an oblique port extending from the bottom of said well to the lower face of the plug and opening near the edge of said plug.
